AbstractThis data report describes a set of laboratory indentation tests that were performed using iceberg ice. The tests were performed as collaboration between Memorial University of Newfoundland and The Institute of Ocean Technology (NRC-IOT). These test represent an extension to a test program that explored the role of flaws on the fracture of polycrystalline ice (Wells et al., 2007 and Wells et al., 2009). In those tests, polycrystalline ice with an average grain size of 4mm was prepared in the lab. The prepared samples included 2 cm cubed monocrystals placed at specific positions within the specimens to represent flaws in the ice. Indentation tests were performed to study the effect that the included flaws had on the ice fracture behavior. In the present tests, iceberg ice is used to bring the tests one step closer to the diversity of flaws that would be found in natural ice.
